The U.S. Embassy in Havana issued a security alert on Monday for American citizens in Cuba due to a total blackout of the national electrical system, which occurred around 1:54 PM local time, leaving the entire population of 11 million residents without power. This blackout marks the third massive power outage in Cuba within four months, highlighting ongoing challenges within the island's electrical infrastructure.

In its communication, the embassy described the Cuban electrical grid as increasingly unstable, stressing that both scheduled and unscheduled blackouts have become a daily issue across the country, including in the capital, Havana. The alert emphasized the broader impacts of such blackouts, which not only affect electricity but also have significant consequences for water supply, lighting, refrigeration, and communications.

This ongoing situation raises concerns for safety and humanitarian conditions on the island, as frequent power outages can severely strain daily life and access to essential services. The U.S. government is urging its citizens in Cuba to prepare for potential prolonged outages, signaling the urgency of addressing the challenges faced by public utilities in the country and their wider implications for Cuban society and its relations with the U.S.
